Abstract

A safety cover of portable gas container includes top and bottom housings, a locking device, and a first opening on the top housing. The top housing is for covering the upper part of the portable gas container, and includes top and side walls, and a space, confined by the top and side walls, for accepting the upper part of the gas container. The first opening through the top wall of the top housing is adapted to expose a nozzle of the gas container. The bottom housing is for covering the lower part of the portable gas container, and includes side and bottom walls, and a space defined by the side and bottom walls. The locking device is for engaging and securing the top and bottom housings. The safety cover of portable gas container encloses the portable gas container and safely confines an explosion of the gas container inside.

Description

    BACKGROUND OF THE INVENTION
  • The present invention relates to a safety cover for a portable gas container.
  • More particularly, this invention relates to a safety cover for a portable gas container that keeps the commercially available gas container from exploding due to some mechanical damages on the canister.
  • Also, the invention is related to a safety cover for a portable gas container, which is able to keep a damaged gas container from being used in a condition that even gas leak is happening.
  • A portable gas container is a convenient choice for fuel. It is small and light. It contains compressed fuel gas of quantity enough to cook several servings of dishes. That is why so many different types of portable burners or cookers use such kinds of portable gas container. The portable cooker using the portable gas container is widely used not only in outings or camping, but also in some indoor events. For the case of power failure, it is the only way to cook to resort to such a portable cooker and portable gas containers.
  • Some problems lie in the portable gas container. The commercially available gas containers are really weak. They are light, which makes the container susceptible to a mechanical shock or pressure on the container. Under the shock and/or external pressure, the thin metal container can be deformed or even fractured especially along the connecting line between the cylinder part and the bottom part.
  • Accordingly, a need for a safety cover for portable gas container has been present for a long time considering the impending safety problem and the popularity of the portable gas burner. This invention is directed to solve these problems and satisfy the long-felt need.
    • SUMMARY OF THE INVENTION
  • The present invention contrives to solve the disadvantages of the prior art.
  • An objective of the invention is to provide a safety cover for a portable gas container.
